The Common European Framework of Reference for Languages (CEFR) is exactly what its title says it is: a framework of reference.
What the CEFR can do is to stand as a central point of reference.
The CEFR describes language ability on a scale of levels from A1 for beginners up to C2 for those who have mastered a language.
The CEFR describes foreign language proficiency at six levels: A1 and A2, B1 and B2, C1 and C2. It also defines three ‘plus’ levels (A2+, B1+, B2+).
This is the CEFR global scale:
Cambridge ESOL (English for Speakers of Other
Languages) exams integrate the CEFR standards.
The equivalences are:
CEFR A2: KET (Key English Test)
CEFR B1: PET (Preliminary English Test)
CEFR B2: FCE (First Certificate in English)
CEFR C1: CAE (Certificate in Advanced English).
CEFR C2: CPE (Certificate of Proficiency in English).
